| Summary: | 碩士 === 朝陽科技大學 === 環境工程與管理系碩士班 === 98 === In the soil organic matter contamination concerns and so on polycyclic aromatic hydrocarbon compound and chlorphenol has received takes seriously. But aromatic compound and cholrphenol in environment. Because natural factor like forest-fire oil quality and organic solvent not, when abandons primarily or humanitys related system regulation like metropolis and the industry activity produces. Again because of water or in air way contaminated soil ground water.
Phytoremediation is an emerging technology for the remeaiation.Using plants for the remediation of the organic pollutant soil. In recent years phytoremediation is an emerging technology of the soil remediation. this study used ryegrass (Lolium perenne) and soy bean (Glycine max) improvement of the organic matter pollution soil. Also added catalysts manganes oxide (δ-MnO2) to compare different treatment the degradation of pyrene.This research carries on increases Pyrene to take the contaminated soil artificially, the use pot experiment planter ryegrass (Lolium perenne) and soy bean (Glycine max).Each treatment had four replicates. Control、not planted、5% OM additions、5% OM additions and 1% MnO2、1% MnO2 additions. The result showed that increases 5% raise earth in the Pyrene density is 150 mg kg-1, 300 mg kg-1, of contaminated soil in 450 mg kg-1, the ryegrass to the Pyrene degeneration rate respectively is 93%, 92%, 89%. the soy bean to the Pyrene degeneration rate respectively is 90%, 93%, 88%. But increases 1% MnO2 in the Pyrene density is 150 mg kg-1, 300 mg kg-1, of contaminated soil in 450 mg kg-1 the ryegrass to the Pyrene degeneration rate respectively is 90%, 90%, 87%. the soy bean to the Pyrene degeneration rate respectively is 89%, 91%, 90%. The result demonstrated that the ryegrass and soy bean pyrene degradation reached to 87%~93%. The control ryegrass and soy bean pyrene degradation reached to 80%~85%. And is increasing 1% MnO2 catalyst to have degeneration of rate the Pyrene contaminated soil the remarkable difference, therefore suggested that if plants by the perennial ryegrass and soy bean phytoremediation processing the Pyrene contaminated soil.
